/*
  Design idea: a dry paddock and a full tank.
  Sand (wheat) is the friendly ground everyone stands on. Deep dam blue carries trust and the trade side.
  Bright water blue appears only where there is water: fills, gauges, results. Wattle yellow means "act".
  One memorable moment: the hero tank drawn at true scale, growing and filling as you answer.
